A Nevada man found sleeping in a stolen truck packed with guns and gasoline bombs was mentally ill but hadn’t planned any mischief.

That’s the conclusion offered by federal prosecutors, who are expected to ask Thursday that Justin Miles Jasper be sentenced to three years in prison for crimes surrounding his July 2013 arrest in Seattle’s University District.

On July 3, University of Washington police found Jasper, 22, sleeping in a Dodge Ram with Montana plates. Police arrested him later that evening after learning the truck had been reported stolen.

Searching the truck, officers found quite the arsenal – a rifle and a shotgun, military body armor and six Molotov cocktails built out of glass beer bottles.

The weapons and armor coupled with a note Jasper left in Montana, stating he was headed to Seattle to argue about politics, prompted concerns that Jasper was preparing some kind of attack. His arrest, coming a day before Independence Day, made national news as some suspected a bombing in the works.

Federal prosecutors now say those worries appear to have been unfounded – no evidence of a plan was ever uncovered – though Jasper appears to be mentally ill.

Writing the court, Assistant U.S. Attorney Todd Greenberg said the investigation into Jasper’s crimes showed he made the firebombs in Montana before stealing the pickup and firearms and driving to Seattle.

Prior to the incident, Jasper had been espousing fringe views online for some time, prompting concerns of a politically motivated attack.

“Despite an extensive investigation, it appears that Jasper did not have any plan or plot regarding the use or possession of the Molotov cocktails or the firearms,” Greenberg said in court papers.

“Jasper appears to suffer from serious mental health issues and seems not to have formulated any specific intent or plans with regard to his trip to Seattle,” the prosecutor continued.

His public defender and prosecutors are expected to request a three-year prison term for the young man. They have also asked that Jasper receive intensive psychiatric treatment while he is in prison.

Greenberg said Jasper created an “extremely risky situation” by possessing Molotov cocktails and stolen guns in a densely populated area. But, with no criminal history, the prosecutor suggested Jasper and the community at large will be best served by the 22-year-old receiving mental health treatment.

Jasper is scheduled to be sentenced Thursday by U.S. District Judge Ricardo Martinez. He remains jailed pending his transfer to the Bureau of Prisons.
